Well said @extractum-lunae. So much has changed, yet nothing has. Personally, as long as someone can play the role and do it justice that is all that matters. Having seen movies which were based on stories and books where in the book a full detailed description is given and not followed in the movie, does bother fans. The cannot get certain things out of their head.

In some cases, the artistic license that is used to 'recreate' a role is more than justified. People need to learn to enjoy what they are watching. Yes, your favorite actor makes it better, but it doesn't mean that I can't be as good or better.

There are 2 roles that come to mind where the changes, I feel worked out better. The Dark Tower. Idris Elba was fantastic. Of course, I don't think he could be bad in anything. The character he played was white in the books. Yes people got upset over that. The movie wasn't 'great' but the acting was good. Another is Tara from True Blood. In the books Tara is white, nice but spoiled, owns a dress shop. In the series... she black, a loud mouth, the complete polar opposite of the books. With out her in the series, it would have lacked some of the appeal.
